.application filed september 27, 191e.

To all/whom zzf may concern Be it known that I, WILSON T. ROBERTS, a citizen of the United States, residing at Columbus Grove, in the county of Putnam,-

State of Ohio, have invented a new and useful Carpet-Cleaning Machine; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as willenable others skilled in the art to whichit appertains to make and use the same.

This invention relates to an improved carpet cleaning machine, and an object of the invention is to provide an efficient and practical machine of this kind, in which improved features of construction are involved.

A further object of the invention is to provide a wire fabric cylinder having an elongated opening at its bottom, so that a carpet to be cleaned may be moved about the cylinder, so that as the carpet passes the opening, the carpet may be automatically beaten to remove the dust and dirt.

A further objectof the invention is to provide means for carrying the carpet about the wire fabric cylinder, in combination with a mechanism for rotating said means.

A further object of the invention is the provision of means actuated by said mechansm for beating the carpet as it moves past the elongated opening along the bottom of the wire fabric cylinder.

A further object of the invention is to provide means` actuated by said mechanism for fanning` the dust downwardly through the opening, that is, to impart a blast of wind against the inner face of the carpet as it passes the opening, so that the dust will be forced down.. A

A further object of the invention is to provide means to hold the carpet adjacent the cylinder and prevent the same frombinding. y ln practical fields, the details of construction may necessitate alterations falling within thel scope of what is claimed.

The invention comprises further features and combinationofparts, as hereinafter set forth, shown inthe drawings, and claimed.

In the drawings Figure 1 is view in side elevation of the carpet cleaning machine, showing parts broken away, to more clearly disclose some of the details of construction.

Fig. 2 is a iongitudinal sectional view.

Fig 4 is a transverse sectional view on line 4 4 of Fig. 1. 4 Fig. 5 is an end view of the carpet cleaning machine, showing the gear connections between the carpet beating means, the fannlng means and the means for rotating the chains, which carry the carpet about the wire fabric cylinder.

F ig. `o is a detail view of a portion of one of the chains, showing the carpet clamping means.

Fig. 7 is a detail sectional view of a part of one of the chains and through the clamp.

Referring more especially to the drawings, 1 designates a base frame, which may be any suitable shape, preferably rectangular, consisting of the longitudinal side and end pieces 2 and 3, and the central piece 4E, and fixed to the top of .the base frame is a piece of wire fabric 5. Rising upwardly from the opposite ends of the base frame are the end walls 6 and 7 of the carpet cylinder 8. This cylinder 8 consists of a plurality of metallic bands 9, which are provided with annular channels 10. However, the bands 9 are n ot completely circular, by reason of the fact that their corresponding lowerportions are cut away, and the opposite ends of each band, where the cutaway portion occurs, .terminate a trifle inwardly from the longitudinal sides of the base frame. The opposite end bands 9 are provided with ears 11, through which suitable screws or the like 12 pass, in order to secure the end bands to the end pieces 6 and 7 of the carpet cylinder. These bands 9 are connected by intermediate wire fabric pieces 13, which correspond in length to the bands 9. Since the bands 9 have their lower portions cut away, and the wire fabric pieces 13 corresponding thereto, it is to be noted that the carpet cylinder is provided with a. longitudinal opening 14 at the bottom. The end pieces 6 and 7 of the carpet cylinder are connected by the longitudinal strips or bars 15, which are spaced in accordance with the width of the opening 14, and to the lower edges of which strips or bars l5 the opposite ends of the bands 9 and the wire fabric pieces 13 are secured by screws or the like 16, thereby rendering the parts more secure and rigid. An arched sheet metal cover 17 is secured to the edges of the end pieces 6 and 7, to cover the carpet, not shown, as

lill() it travels or moves about the cylinder, there being a longitudinal strip 18 extending along the top of the cover 17, and secured in any suitable manner to the upper edges of the end pieces 6 and 7. Connected to the lower edges of the arched cover by means of suitable hinged connections 19 are closures 20, which may be opened, when litting a carpet upon the cylinder, or when removing a carpet. Extending about the bands 9 and moving in the channels are suitable chains 21. At corresponding points on said chains clamps 22 are pivoted, as at 23. Each clamp consists of the two plates 24 and 25,which have arms 26 mounted upon the pivot 23. The arms of the plate 25 fit between the arms of the plate 24.

, The plate 24 has an integral screw 27 eX- tending through an opening 28 of the plate 25, anc is provided with a winged nut 29 for drawing the two plates toward veach other, to clamp one edge portion of a carpet or rug between them, as shown in Figs.

6 and 7, there being spurs 30 carried by the plate 24, to pierce the carpet and extend through the plate 25 to insure holding the the two clamping plates. Secured by rivets or the like 31 to the upcarpet between per inner face of a cover 17 are spring'arms 32, to the corresponding ends of which a rod 33 is connected in any suitable manner. This rod 33 bears upon the carpet, and holds the same closely against the fabric cylinder. Mounted in bearings of the end pieces 6 and 7 are the shafts 34 and 35, which are provided with sprocket wheels 36, with which the carpet carrying chains engaga,

of the bands 9. Mounted in bearings of the end pieces 6 and 7 are the pintles 37 and 38r carpet beating chain 41 is so connected to the eyes, so as to form loops, and the loops of one chain are in staggered relation to the loops of` an adjacent chain, so as to insure beatingall parts of the carpet as it passes the longitudinal opening. The pintle 38 ofthe shaft 39 is provided with a gear 42 and, a sprocket wheel 43, about which a sprocket chain 44 (which may be operated from any suitable source of power, not shown) travels, so as to impart revoluble movement to the shaft 39. A stub shaft 45 is carried by the end piece 7, andhas a gear 46 thereon. Also mounted in bearings of the end pieces 6 and 7 is a shaft 47 -provided with radial arms 48, to which the fan blades 49A are `connectedin. any suitable man-` liefe One @ed O fthe Sheff 47,11%@ s631150,

so that when the shaft 34 is rotated,A the chains 21 will move in the channels 10` which meshes with the gear 46, so that when the shaft 39 is rotated, the shaft 47 will correspondingly rotate. In this case, the fan blades will generate a volume of air, which tends to percolate through the carpet as it passes the opening 14, to insure forcing the dust and the like downwardly, so as torremain below the wire fabric piece or strip 5, that is, as the carpet beating chains are constantly striking the carpet. A second stub shaft 51 is carried by the end piece 7, and is provided with a gear 52, which meshes with a gear 53, which is also carried by the stub shaft 45. On one end of the shaft 34 a gear 54 is keyed, and which gear 54 meshes with the gear 52, so that whenY the gear 46 (which, together with the gear 53, arecarried by a sleeve 55) rotates, the gear 52 is correspondingly rotated through the medium of the gear 53, thereby imparting motion to the shaft 34, which in turn through the sprockets 36 of the shaft 34, will rotate or move the chains through the channels 10, andV being that the carpet is clamped to the chain, the carpet will be moved about the cylinder in order to be beaten. The end pieces 6V and` 7 areprovided with openings 56, to permit air to enter the cylinder. Air through the openings 56 may be regulated by manipulating or opening the closures 57, which are pivoted upon the pins 58.

The invention having been set forth, what is claimed as new and useful, is

1. In a carpet cleaning machine, the combination of a casing and a wire fabric cylinder mounted therein having annular channels, of means movable in the channels to carry a carpet about the cylinder, said cylinder having an opening in its bottom over which the carpet passes, and a revoluble member rotatable adjacent the opening and provided with beaters to strike the carpet as it passes over the opening. l
